Q:Selection of Circuit Breakers in Low Voltage Circuits

The thermal circuit breaker uses a bimetallic plate in series with the circuit. The heat generated by the current during the overload causes the bimetal to deform, causing the circuit breaker to trip

Q:s the MCB switch a circuit breaker or a component on the circuit breaker?

The determination of the total switch circuit breaker in the household distribution box is determined by the sum of the rated current of all the branch circuit breakers in the distribution box

Q:What is the capacity of the circuit breaker

the maximum short-circuit current of the circuit breaker can ensure the breaking current is the rated breaking current.

Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?

You said the knife can be understood as a kind of isolation switch, it is only as a circuit break point, no lines, load protection function

Q:Home no electricity corridor switch the total switch circuit burned how the matter

The circuit breaker in the circuit breaker indicates that the circuit breaker with the numbe

Q:Circuit breaker main circuit control power, how to wiring?

which should be not less than the effective value of the short-circuit current at which the contact begins to be separated) by the rated voltage. Of course, to single or three-phase. for reference only.

Q:Is the circuit breaker in the circuit necessary?

When the air is open, it is not recommended to use the fuse, need to protect, open the three-phase at the same time off, such as with the fuse

Q:What is the choice of low voltage electrical circuit breaker?

This feature is often useful when the circuit breaker and the system are exposed to the same heat source. In this case, the protection circuit can track the equipment at higher temperatures for enhanced wiring protection requirements

Q:What circuit symbols are used for circuit breakers

mass I + I + I <phase = nine = 0. Mass or I + I + I <phase + = nine = 0. So the brothers must install the ground wire ah

Q:What is the specific function of the auxiliary switch on the circuit breaker switch?

Used to control, protect, adjust, measure and monitor the parameters of the circuit and the working conditions of each component.
